So to build this game, I’m using XNA – the C# game framework by Microsoft. Yes, yes, I know, ‘learn Flash/Java/whatever else’ – and one day I will, but not yet.

Anyway, with 15 hours left, I haven’t gotten anywhere near monster encounters and map changing, because I’m still on this b*tch of a problem – collision detection using a colour key.

I’m doing a cave exploring game (no points for originality), and for some reason, even after I drew it a nice map to stick to, still won’t let you move around because it thinks you’re slamming into some kind of invisible wall. I don’t get it.

Ugh!

BTW, thoughts and ideas are welcome in the comments. Don’t link me to endless tutorials though – I know how to use Google.
